"An animated suit of thick metal and armor, this blade golem is a fearsome automation bound to its controller’s will. Its right arm is a blade as long as a grown human. The armored plates of this golem have a metallic blue sheen and the styling of the armor is unlike the fashion of armor found in the Sword Coast. Standing well over eight feet tall, this metal giant moves with remarkable speed and grace despite its mass."

The Construct has very good stats (Str 26 Dex 14 Con 22 Int 14 Wis 10 Chr 8). He only specializes into his own creature weapons, which however cannot be enchanted in any way. As a construct, he is immune to many things, like mind manipulation, sneak attacks, and critical hits.

As a pure fighter acquired in the second chapter, the Construct isn't very customizable, though he is specced well for what he does. Theoretically, the player can also apply several enhancements through the use of Craft Alchemy, Craft Weapon, and Craft Armor. Due to programming failures, however, this section of the Construct's dialogue is bugged to the point that succeeding will provide (nearly) nothing. With the Alchemy upgrade, if you fail in the attempt and Sand is in your party, he will speak and reluctantly offer to help. If you let him, he will do the upgrade for you, which may do nothing or may apply the Warlock feat Resist Fire and Energy.

A totally untrained Intelligence 14 character can pass the DC 15 needed in each of the skills, with the help of a Headband of Intelligence +8, Grobnar's Inspire Competence, a Greater Heroism spell, and the Greater Gloves of the Artificer.

In theory, these upgrades offer the Construct a +3 AC boost with the armour improvement, a +6 Strength the weapon boost, and +15 hit points with the alchemy upgrade. Due to a bug, he instead gets 5-point resistances to fire, cold, and electricity. These resistances upgrade to 10 points when the Construct reaches level 20. (See the talk page for a way to correct the bug using console commands.)

After killing the Shadow Reaver who carries the Tome of Iltkazar, you can use it to upgrade the Construct further. Have the tome in your inventory, and both Grobnar and the Construct outside of your active party. Talk to Grobnar and ask him to use the tome to upgrade the Construct. The Construct will gain +2 to STR, DEX and CON.

The Construct is a Blade Golem first seen when Black Garius sends it against the Githyanki assassins that were hiding in Neverwinter. It attacks both the Githyanki and PC party and after being damaged enough escapes through a Githyanki portal and is captured. The Githyanki somehow manage to damage it and render it inert. The PC comes across the Construct again when rescuing Shandra in the Githyanki's stronghold where it is being torn apart by Ammon Jerro's demons. After rescuing Shandra, the PC brings the Construct back with him/her and Grobnar attempts to repair it. A minor quest is activated where the PC must find parts in order to help Grobnar repair the Construct. Shortly before the Construct is reactivated, Bishop manages to trick Grobnar into giving him the override code for the Construct.

The final fate of the Construct is determined by the PC's influence with Bishop and Grobnar. If the PC has high influence with Bishop, the Construct remains under Grobnar's control. If the PC has low influence with Bishop and low influence with Grobnar, Bishop gains control of the Construct with the override commands and uses it to fight against the PC. If the PC has low influence with Bishop but high influence with Grobnar, Bishop will initially succeed in gaining control of the Construct but Grobnar will reveal that he has another set of override commands which grant the Construct free will. The Construct then decides to side with Grobnar and the PC against Bishop and Black Garius. It is assumed to be missing along with the PC and Grobnar after the defeat of the King of Shadows.
